Structural Characteristics of Single Stage Double Suction Split Casing Pump

1, Compact structure
Nice appearance, good stability and easy installation.
2, Operate steadily
The double suction impeller which is optimum and designed by computer, and has a large inlet flowing area. The clapboard is set at packing box of inlet flow passage, it makes no vortex at inlet of pump. It adopts resin sand moulding and high quality cast technology to make the inner surface of pump casing and the surface of impeller smoother than before. Through above measures, we make pump operate with no vortex, operate smoother and have remarkable erosion-resistant ability and high efficiency.
3, Bearing
Excellent bearing is used to assure the steady operation, low noise, long service life. Grease lubrication and closed structure is used. If thin oil lubrication structure is needed, a constant level oil cup shall be equipped.
4, Shaft seal
Mechanical seal or packing seal shall be used. These two kinds of seal are all installed in the removable packing box, which is convenient to assembly and maintenance. The packing gland of pump is removable and open, which assures enough room for maintenance and repair.
5, Impeller
The latest technology is adopted as well as the best hydraulic model, which makes the double suction impeller can balance the axial force automatically.
6, Shaft
Shaft is completely sealed without contacting the medium or corrosion. The length of the shaft is shortened compared with that of S, SH type pumps, and it is hard with no vibration. A replaceable shaft sleeve is installed on the shaft. There is no thread on the shaft, and o-ring structure is adopted to assure shaft and bearing do not contact the medium to improve the service life. It is easy to assemble without adjustment. Pump rotor part shall be installed with elastic prestressing force, which makes the installation and disassembly much easier and more convenient.
7, Casing
For the pump of high head, double split casing passage is adopted, which counteracts most of the radial force and prolongs the life of bearing on two sides.
According to the different mediums and using requirements, main parts of the pump can adopt various materials



Q: Can your pumps mount Eff.1 motors

A: Currently, only on request though this will shortly be a CNBM standard.

Q: Are your pumps protected against dry running?

A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

Q: How can I get trained on CNBM products?

A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.

Q: Are your pumps cheaper than those of your competitors?

A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.

Q:Do i need a new water pump?
The radiator actual holds the water/coolant and the pump circulates the combination in the process the engine. Upon returning to the radiator, the water is cooled from air passing in the path of the fins of the radiator. The pumps activity is to circulate the combination to confirm that the nice and cozy water to relax for this reason, the engine is then cooled.
Q:where is the water pump for a 2001 chevy malibu?
On When you're filling up the coolant, you need to bleed the system to get the air out. 2 bleeders, one right around the corner from the pump, and another back by the Thermostat housing. The 3.1L V6 in your Malibu doesn't use a timing belt, but a chain. Just take the serpentine belt off, take the pulley off, and there's the pump. 4 bolts for the pulley I think, and 5 for the pump. Easiest to loosen the pulley bolts, then do the final tighten later, while the belt is still on. Torque the Water pump bolts to 89 inch lbs. (10 Nm), and the pulley bolts to 18 ft. lbs. (24 Nm)
Q:What is the influence of the speed of the pump motor on the pump?
Low speed, the pump has a certain wear and tear
Q:what am I doing wrong with my water pump install?
the wheel that holds the 3 belts that goes onto the water pump is called the pulley. You may need to check the old water pump for a spacer between the pump and the pulley. If the tube is not straight you may need to turn it some. Verify that you are not putting the pulley on backwards. Although the auto parts store claims that it is the right water pump, they may be wrong, and may have given you the wrong one. To find out lay the side that goes against the engine on a flat surface next to the original to see if the height is the same for the shaft that the pulley goes on. If you cannot solve this you may want to take both water pumps, the pulley, the bolts that hold the pulley on and the tube for the heater hose to the auto parts store and ask them. Often they have some experience in automotive repair and may be able to show you...the main difference between them and us is they will be able to see the parts, and we cannot.
Q:Safety head of water pump?
The pump achieves this by providing sufficient energy to the liquid at the entrance of the impeller, and ensuring that the liquid remains liquid. This energy is known as the available cavitation margin, referred to as NPSH (A).If there is not enough NPSH (A) or energy, as soon as the liquid enters the impeller, its velocity is increased. According to Pohl's law, the pressure drops. A reduction in pressure will cause some molecules in the liquid to become gaseous, forming vapor bubbles.The performance of the pump will be lowered immediately and the bubbles will continue to grow until the pressure inside the pump causes them to implode.In brief, it is to avoid cavitation.
Q:Well water pumping system?
the only way to check it is to have a well pump service pull the pump and check the verticle lines. they tend to rust out. you can have them replaced by pvc lines now. when our pump went out we had all of the lines replaced because several of the galvanized lines had pin holes in them
Q:how to install a main pipe water pump to service the community?
Installation of water pump is very easy, any certified plumber and electrician can install electric water pump. Your question maybe is, how to design water pump water system to service the community? To determine the correct rating of water pump to be used and to design a water system, here are the steps : 1) Determine the safe discharge yield of your well for your water source, by series of tests. This will enable you to know discharge rate of well and the draw back time of water after pumping. This data will be used for designing a pump (its discharge capacity). Note that pump discharge capacity should be lower than well safe yield capacity in order not to drain the well. 2) Determine the suction lift or height of water table in the well by measuring the height from water table up to the top of the well. This data will be used for pump design (its suction lift/height capacity). Pumps suction lift varies depends on its Horsepower capacity and the type of pump (submersibble or centrifugal). 3) Determine number of households in the community. This data will be used for the design of reservoir (tank) for your water system and the number of hours for the pump to operate to fill the tank. Note that the average usage of water is 120 liters per day per capita. So the more the number of population, the bigger the tank and the longer the pumping time in order to meet the per capita usage. 4) Determine the elevations from your water source towards the community to be served. Use survey instrument to determine the elevations. This data will be used to design a height of the tank and the sizes of service pipes towards the community. The higher the difference in elevation from your source towards community, the lower the height of the tank and the smaller the sizes of service pipes. Sizes of service pipes can be determined by hydraulic heads (heights). By following these steps, I gues you can now design and construct a water system.
Q:Who can tell me such water pump medium flow direction should be what kind of, from left to right, or from right to left, is low into the higher?
Low inlet and outlet
Q:Do you need a stop valve for the pump at home?
It is better to connect with the pump. If it is a self suction pump, it can not be connected, but when it is pumped, it does not immediately have water, and the submersible pump is not necessaryMy home is a self suction pump, fully automatic control, I took the check valve, in the pump suction port position is very good, as long as it has started, there will be water out
Q:What size water pump should I get?
A 3/4 horse pump usually has a one inch suction and 3/4 inch outlet and is more than enough to water one acre. Remember, you don't have to water every day or even cover the entire acre all in one day. The industrial/agricultural pump mentioned before (4 inch? 6 inch? Or more?) is intended for use on dozens of acres per day.
